Split system air conditioners are the most popular cooling and heating solution for Perth homes, and it's not hard to see why. They're affordable to install, efficient to run, don't require major structural work, and can be fitted to almost any room in a home or small office. If you're looking to install a new split system in Perth — whether it's your first unit or your fifth — getting the installation done properly is what determines how well the system performs for the next ten to fifteen years.
We install split system air conditioners across Perth for homeowners, landlords, renters (with owner approval), and small businesses. Every installation is carried out by licensed technicians, sized correctly for the room, and fitted to Australian Standards.
A split system consists of two main parts: an indoor unit mounted on a wall (or occasionally the ceiling or floor) inside the room being cooled or heated, and an outdoor condenser unit that sits outside the property. The two are connected by refrigerant piping and electrical cabling run through a small hole in the wall. Because there’s no ductwork involved, split systems are far less invasive to install than ducted alternatives, and they cool or heat a single space very effectively.
Most split systems installed in Perth today are reverse cycle, meaning the same unit provides both cooling in summer and heating in winter. This makes a single split system a genuinely year-round solution for a bedroom, living area, home office, granny flat, or small commercial space.
Compared to ducted systems, split systems are significantly cheaper to install because there's no ductwork, minimal structural work, and a shorter installation timeframe.
Each split system operates independently, so you're only running and paying for cooling or heating in the rooms you're actually using.
Modern split systems, particularly inverter models, adjust their output to match the room's needs rather than cycling on and off at full power. This keeps running costs down and maintains a more consistent temperature.
Split systems can be installed in almost any room, including additions, granny flats, home offices, and rooms in older homes without existing ductwork.
A standard single split system installation is typically completed within a day, meaning minimal disruption to your household or business.
From small bedroom units through to larger systems for open-plan living areas, split systems are available in capacities to suit almost any room size.
We visit your property and assess the room you want cooled or heated — its size, ceiling height, window orientation, insulation, and where the outdoor unit can realistically be positioned.
Getting the capacity right is the single biggest factor in how well a split system performs. An undersized unit will run constantly and never quite reach temperature; an oversized unit will short-cycle, leading to poor humidity control and unnecessary wear. We calculate the appropriate capacity for your specific room rather than guessing.
We work with a range of established air conditioning brands and will talk you through the differences in efficiency, noise levels, warranty terms, and price so you can choose confidently.
You'll receive a clear, itemised quote covering the unit, installation labour, and any additional work required (such as extra bracketry, longer pipe runs, or electrical upgrades).
Our licensed technicians mount the indoor and outdoor units, run and insulate the refrigerant lines, complete the electrical connection, and pressure-test the system for refrigerant leaks.
Once installed, we test heating and cooling function, check airflow and drainage, and walk you through operation of the remote or smart controls. You'll receive warranty documentation covering both the unit and our workmanship.
Split systems are suited to almost every part of a Perth home or small business, including:
If you have multiple rooms that need cooling and heating, we can also advise on whether a multi-head split system (one outdoor unit running several indoor units) makes more sense than installing several fully separate systems.
A single split system connects one outdoor unit to one indoor unit, and is the right choice when you’re cooling or heating one room. A multi-head split system connects one larger outdoor unit to two, three, or more indoor units placed in different rooms.
Multi-head systems can be a more space-efficient and sometimes more cost-effective option if you need several rooms covered and don’t want multiple outdoor units cluttering the exterior of the property. We’ll assess your property and needs and give you an honest comparison of the costs and trade-offs of each approach.
Several factors influence the total installation cost:
We account for all of this during the free site assessment so your quote reflects the real scope of the job, not just a base unit price.
We install split system air conditioners across the greater Perth metro area, covering homes and small businesses in the northern suburbs, southern suburbs, eastern corridor, and inner-city precincts. Get in touch to confirm coverage for your specific suburb.
A standard single split system installation is usually completed in around half a day to a full day, depending on wall type, pipe run length, and access.
Capacity depends on the room's floor area, ceiling height, insulation, window size and orientation, and how the room is used. As a general guide, small bedrooms typically need less capacity than open-plan living areas, but we always calculate this on-site rather than relying on a rough per-square-metre rule, since factors like north-facing windows or poor insulation can significantly change the requirement.
No. In Australia, the installation of refrigerant-containing air conditioning systems must be carried out by a licensed technician. This isn't just a formality — improper installation can lead to poor performance, refrigerant leaks, and voided warranties.
Yes. Regular servicing (generally annually) keeps the system running efficiently, prevents dust and mould build-up in the filters and coils, and catches small issues before they become expensive repairs.
Most split systems installed today are reverse cycle, meaning they provide both heating and cooling from the same unit. This is almost always the better choice for Perth's climate, where you'll want heating in winter as well as cooling in summer.
Yes, provided the landlord or property manager approves the installation. We're happy to provide documentation and quotes suitable for landlord approval processes.
We work with a range of well-established air conditioning brands and will recommend options based on your budget, efficiency requirements, and the specific demands of your space, rather than pushing a single brand across every job.
